My mom took me to the doctor, and he said it was a fungal infection. He didn't give me any drugs for it, but told me simply to soak my hands two or three times a day (I can't remember for sure but I think it was two) in dish soap water for 15 minutes each time. He also said to go to the drug store and get some acidophilus pills and take those every day. I did this for a week or two (I made the dish soap water quite soapy) and the infection totally disappeared, and my nails grew back to perfectly normal.
